1. An ATP connector on a solar charging system experienced a high resistance event and started a smoldering fire. It melted the connector and about 24" of 10 gauge wiring. It also melted the fiberglass roof material under the connector. The event was observed on Sunday morning, April 19, 2026 at approximately 9:30 am. It occurred while parked in our driveway. We disconnected the solar panel that was feeding this wire to remove the resistance to the system and stop the damage from spreading. 2. Had we not seen the smoke, a major fire could have destroyed the RV and endangered our house. 3. Problem was reported to the manufacturer who seemed most concerned that the RV was no longer in warranty. The damage was observed and repaired by a factory authorized service center on Monday, April 27, 2026. 4. There were no warnings.
